SPECIFICATION forming part of LettersPatent 'No. `294,500, dated March4, 18861.`

Application led J'uly 28, 1883. (No model.)

To all whom, it may concern.-

Be it known that I,WILLIAM R. PATTER- V SON, a citizen of theUnitedStates, residing at l telegraph-cables; and it consists inapparatus been done by hand. The core being laid in pipe. vstructed thattheir diameters may be dimmfor drawing acore of insulated electricalconductors into sections of pipe. Itis desirable that the core should beof considerable length. The pipe, which is usually of lead, may be inShorter sections. I find it convenient to use sections of pipe of aboutone hundredfeet in length, while the section of the core' may be athousand feet or more in llength. lHeretofore the'work of drawing intothe pipe has a coil is drawn into the first section of pipe and theportion of-the core not covered by the iirst section is again carefullyformed into a coil and then .drawn through the second Section of pipeand a coil again formed at the end of the second section. rIhe operationis repeated until all the coreis covered. rIhe greatest care is requiredin eoiling and uncoiling the core to prevent kinking. the wires, whichare liable tobe broken notwithstanding the greatest care may beexercised, and especially when the wires are quite small, as intelephonecables.

By the use of my invention as herein described I am enabled to cover avery long core with pipe by mechanical power without the necessity ofrepeatedly coiling and uncoilingthe core, and without injury to theconductors. I am thus enabled to manufacture telegraph-cables which aremore reliable than those made heretofore, while the work is at the sametime greatly facilitated.

The mechanism which I have devised to carry out my invention consists incapstans of novel construction, which` may be arranged in series to drawthe core'through the sections of These capstans are preferably so convished so as to allow the core to slip off from any one capstan. AThesecapstans I have found it convenient to arrange horizontally in tworowsvnear the oor, with mechanism under the floor for driving themuniformly. The sections of pipe are arranged upon the floor, the end ofeach section being held by a socket or holder secured in front of eachof the capstans. The cord by Which the core is to be pulled in is thenrun .through all 'the sections of pipe and around the capstans. Bystarting the driving mechanism the core may be drawn directly from areel into the pipe arranged in sections, as described. By slipping offthe core from the capstans, one after the other, and bending the ends ofcorresponding sections of pipe, so that one may be slipped into the endof the other, the slack of. core between the different sections may betaken up by starting the driving mechanism. After the core is thuscovered with the sections of pipe, the joints are wiped, and then theparaffine or other `insulating material may be forced into the pipeabout the core, thus completing the cable. I

have provided frictional pieces upon the shaft of each capstan, which'are so adjusted as .to clamp the hub with Suflicient force to cause thecapstan to move with the shaft underA ordinary circumstances. If,however, the core should kink or become obstructed in its movement forany reason, the friction resistance between the frictionpieces and hubwill not 4 tion there will be only a limited strain upon `the wires,since the friction upon the capstanswill not be suflicient to cause themto revolve. I have illustrated my invention in the accompanyingdrawings, in which Figure 1 is a plan of my system, showing thirteencapstans placed between fourteen sections of lead pipe. The core iswound on'the lower reel, and a 4cord* attached to the end of the corepasses through the sections of pipe` and around the capstans insuccession to the reel Shown at the upper right-hand cor-ner of thedrawings.

Like parts are indicated by similar letters of reference throughout theseveral views.

The gearing or driving mechanism a is placed preferably under the door.The belt b runs upon a loose pulley, which is provided with afriction-clutch. This friction-clutch may be operated in any well-knownway, preferably by leversplaced within reach of workmen at either row ofcapstans. Power may thus be applied and taken off instantaneously. Thecapstans may thus beset in motion and stopped as desired. The core ofthe conductors should be formed into a coil upon the spool or reel c.The sections of piped may be, say, seventy-five feet each in length. Thefront end of each section is placed in a' socket or holder, c. Thissocket may be adjusted to different sizes of pipe by inserting orremoving the adjustingpieces e. Shown in Figs. 8 and 9.) The interiorofthe pipe should come Hush with the inner edge of the holder, so thatthe core may be drawn through as freely as possible while the pipe isheld by the edges of the holder. The sections of pipe are placed tangentto the capstans, as shown, so that the cord and core may be drawnthrough them with as little friction as possible.

I will now describe my capstan in detail as shown in Figs. 3, 4, 5, 6,and 7.

The shaft f is driven by any suitable mechanism, as before described,turning in the bearing g, which may be fixed to the floor, as shown. Ihave provided the duct 7L for lubrieating the bearing. The friction-cone t' is keyed to the shaft, so as to always turn therewith. The hublc is held between the frictionpiece l andthe cone, the washer, which isprovided with the feathered key, preventing the adj usting-nut n frombeing turned.

The barrel o of the capstan is composed preferably of four whelpscarried by the pins or arms p p. Links q, pivoted to the collar q', arealso provided. By means of the lever q this collar may be turned, asindicated by the dotted lilies in Fig. 3, and thus the circumference ofthe barrel maybe diminished, so that the cord or core, as the case maybe, may be slipped off. The ratchet g is arranged to hold the lever inany desired position. The whelps, it should be observed, are moveddirectly to and from the center, slipping upon the pins, as shown, whenthe collar is turned by the lever. By means of the adjusting-nut anydesired amount of friction may be obtained between the friction-piecesand hub. The reel r is also provided with similar frictional mechanism,so that it may not be turned with sudicient force to strain or break thewires of the core in case the core for any cause is caught so that itcannot be drawn through the pipe. After the core is drawn into the pipe,I bring the different sections of the pipe together in the followingmanner: I slip the core off from the rst capstan and then bind the twoends of the sections around so that one end will be opposite the other.I then start the driving mechanism, and thus taking up the slack betweenthe two ends of the sections of pipe the end of one section is slippedinto the end of the other for a short distance. I repeat this operationat each capstan in order until all the sections of pipe are joinedtogether and the core covered with a continuous pipe. I then wipe thejoints of the pipe in the usual manner, and then force in the meltedparaifine charged with gas .or other insulating substances in the wellknown way.

I claim as myinventicn and desire to secure by Letters Patentl. rI`hecombination of capstans arranged in rows with mechanism for driving thesame uniformly, and frictioudevices upon the different capstans, wherebythe core may be drawn simultaneously through several sections of pipewithout danger of breaking the conductors, substantially as and for thepurpose specified.
